Hi. I have raynauds. I am 49 and am starting uni. I have to walk to the train station which is 10 minutes away , wait 10 mins for train then travel for half hour. I am worried as usually I have to know where there is a hot tap to run my hands under and as I am going to be travelling for nearly an hour with no access I was wondering how long can ones fingers stay white without it been a problem? I have bought the silver gloves and layered with another pair of gloves, I wear two woolen thermals, a teeshirt, a cashmere jumper, woollen jacket and gloves and still managed to get white fingers last winter. Shaking them out seems to help sometimes but my doctor did scare me as she said if you cant get the blood back in it becomes a medical emergency! Whenever it happens which seems to now be more regularly I get myself into a complete panic trying to get the blood back into the fingers. ANy suggestions and does anyone know if it is dangerous to have white fingers for over an hour??
